Silicon Carbide Brick is an exceptionally tough and adaptable refractory material, capable of withstanding extreme temperatures, mechanical stresses and chemical corrosion – essential features in furnace and kiln lining for iron/steel production, ceramic manufacturing or glassware production.
SiC bricks are constructed using black silicon carbide as their main raw material and a soft clay binder, producing high-performance material with superior oxidation resistance, chemical shock stability and thermal conductivity.
High Temperature Resistance
Silicon Carbide Bricks offer superior thermal resistance when used to line furnaces, kilns, or other heat-intensive equipment, such as furnaces or kilns. Their excellent heat distribution capabilities reduce heat loss significantly while simultaneously helping ensure stable operating conditions.
Silicon carbide bricks provide outstanding chemical stability and oxidation resistance in harsh environments, as well as resistance against corrosion from slag, alkalis, and acids – essential qualities in foundry applications and gas turbine combustion chambers.
AGRM’s premium SiC bricks are manufactured using black silicon carbide as the main raw material and soft clay binder to form a porous structure via reaction sintering process, producing high mechanical strength to withstand heavy loads and pressures, excellent dimensional stability, rapid temperature fluctuations as well as corrosion-resistance against iron corrosion – key features when used as lining material in crucibles or ladles that come into contact with liquid metals such as ladles. They offer exceptional mechanical strength that allows it to withstand such environmental forces, while providing exceptional dimensional stability as lining material is designed to withstand such elements of this environment.
Chemical Resistance
AGRM’s high-performance silicon carbide bricks are the ideal protection in environments exposed to extreme temperatures and chemicals, such as blast furnaces or ceramic kilns. Their strong mechanical strength enables them to withstand stresses caused by heavy loads or stresses from these demanding environments.
Silicon carbide bricks offer the benefits of resilience at elevated temperatures without succumbing to thermal shock, thanks to their low coefficient of thermal expansion. Furthermore, this flexible material can accommodate rapid temperature fluctuations without jeopardizing its structural integrity.
Silicon carbide bricks are composed of silica and carbon grains held together with a binding agent such as clay or silicon nitride, depending on the application. A thorough mixing process is used during production to evenly distribute both binder and powder across the brick body, helping prevent loose bonding or small cracks and thus ensure its success, performance, durability, and longevity.
Abrasion Resistance
Silicon comprises the main constituent of these bricks, giving them exceptional heat resistance. This enables the bricks to withstand high temperatures without losing structural integrity – perfect for harsh environments where damage-inducing temperatures often exist – without losing their structure integrity and bearing damage from high temperature exposure. Furthermore, their thermal expansion rate is very low while they also boast high density.
Silicon carbide bricks have the properties that make them perfect for use in furnaces and other heat-intensive equipment, as well as waste-to-energy plants for lining combustion chambers and flues. Silicon carbide bricks also play an essential role in steel industry electric arc furnaces and ladles contacting molten metal, providing strong protection from high temperatures, chemical corrosion and mechanical stress.
Manufacturing process of silicon carbide bricks starts by shaping them to your desired dimensions using clay, silicate, or mullite as binding agents. They are then dried off to eliminate excess moisture for greater dimensional stability and durability before being exposed to high temperature firing (known as sintering) in special kilns or furnaces in order to combine with raw materials in an attempt to produce high quality silicon carbide bricks.
Low Thermal Expansion
Silicon carbide bricks feature a low thermal expansion rate, meaning they don’t expand or contract significantly with changes in temperature. This helps prevent thermal stress and cracking as well as offering long-term durability in high temperature environments.
These bricks are also highly resistant to chemical corrosion, withstanding harsh chemicals, acids, alkalis, and even molten metals without degrading over time. This makes them suitable for industrial applications requiring both high temperature resistance and chemical stability.
